The appointment was made by a special meeting of all 22 Ballymena councillors. A fair employment tribunal was told that during refreshments after the interviews all 12 members of the Rev Ian Paisley's Democratic Unionist Party had sat at a table on their own. The Protestant man was chosen by a vote of 12 to 10.
Also in July, Limavady council was found guilty of discriminating against a Catholic in the appointment of a chief services technical officer.
A tribunal heard that Unionist councillors had held a private meeting before the interviews to discuss the applicants. The appointment was made by eight votes to seven, eight Unionists voting in favour and seven nationalists against.
